SUPPORT FOR ELECTRIC CONDUCTORS.

SPECIFIGATIGN forming part of Letters Patent No. 758,324, dated April 26, 1904.

Application filed January 24, 1903.Y Serial No. 140,375. (No model.) l

To @ZZ whom, it may concern:

Be it known that I, FRED CHARLES Lookin, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Supportsfor Electric Conductors, of which the following is a specication.

The invention about to be described relates to the distribution oi electrical circuits esductor will easily pass through and a twisted pair of conductors may he entered the rings sidewise. The span-wire is secured to the sides of poles or other supports by brackets or may be suspended from cross-arms, as preferred.

The present invention relates to impovements in the apparatus disclosed in said patent and in the mode of arranging the rings or conductor-suspension supports upon the spanwire. In the said'patent the rings are placed upon the span-wire and one or more linemen l suspended in boatswains chairs are pulled along the span-wire while they space the kept in their distance apart and locked to the span-wire, all of which l will now proceed to kdescribe and claim.

Referring to the drawings, which illustrate and form a part of this specification, Figure l is a side elevation of a span-wire upon which are rings shown as carrying insulated conductors. Fig.' 2 is an end view of the same. Fig. 2 is an edge view of a ring or support, showing the opposite side than ot those sho wn in Fig. 1. Fig. 3 is a plan view oi a span-wire supporting rings or supports in which is represented a cable. Figs. 4, 5, 6, 7, and 8 are detached side viewsof various means for linking, spacing, and locking the rings or supports to one another and to the span-wire. Y

In the drawings, A represents the rings or supports employed to inclose the conductors and cables and suspend them from the spanwire B. The ring is preferably made from iron or steel and galvanized, the main portion being in Vthe form of an eye, one end thereof` extending upward and fiat-tened and reversed upon itseli to form a short hook c, through the parallel sides oi' which are drilled the holes e e. The eye portion is preferably made in cross-section with an inward curve and of thin material in 'order to secure a rounding surface for the conductors f and cable D to slide and rest u-pon and to make the ring rigid and of light weight. There is an opening into which a single conductor can pass. v

Fig. 4 represents a piece of ber, as marlin, prepared to resist moisture, with a portion, as g, brought out in the form of a closed loop, and Fig. 3 is the top view of a span-wire B, upon which are strung rings A by their hooks c. The marlin loops are successively made on the string C and have been drawn through the holes e e in the hookc, brought around to the single marliu and tied thereto, the rings being properly spaced, and as the tiesA are made the rings are drawn along the span-wire until its length is filled, when the marlin at each ,end is fastened to some rigid support and the whole length kept spaced, and as each marlin loop passes under the tie-wire each ring is locked thereto and cannot be moved IOO up or down or sidewise. In case it is desired to remove the rings the marlin ends are unfastened and a leading' or pulling wire attached and the entire length moved ofi'1 from the spanwire.

Fig. 5 shows a form of locking-link composed of wires (lwith eyes m at each end made the length that two rings A are to be separated, usually about two feet, and linked together by the wire pin g, whose eye end connects through the eyes m of two links. The pin g is passed through the holes e e in the hook c of the ring and bent over, thus securing the spacing of the rings and locking them to the span-wire.

Fig. 6 represents what may be a continuous long Wire C, having eyes j made in it the distance the rings are to be spaced, and in each ring is a pin g, held. by its eye z', whose end is adapted to pass through the hook c and be bent over, as indicated in dotted lines.

In Fig. 7 are shown the ends g of two linking-Wires of the length of the distance two rings are spaced, both of which are passed through the holes e e in the hook c of the ring and bent in opposite directions, and by Fig. 8 is represented a form of spacing'and link-A ing similar to that shown in Fig. 4:, closed loops g being made at regular intervals, ex-

cept that it is to be constructed ofmetal wire instead of marlin. rl`he closed loops g are passed through the holes c e in the hooks cof the hooks and bent over under the span-wire.

The form of linking device represented by Figs. l and 2 consists of a straight piece of wire C, having short pieces g bent around the same two or three turns, as L, to .hold tightly thereto at suitable spaced distances, and the pin portion g serves to lock with the hook c. Ample space, as d, is provided for the passage of the span-wire to the hook c and for the ends of the bent-over pins g. By this method of Stringing the rings on the span-1 wire great economy in labor is secured, the rings are accurately spaced and held in their positions, and they are securely locked to the span-wire, and when in position I am enabled to draw single pairs of conductors f or cables D through them with equal facility.

As shown in Figs. l, 2, 2, and 3, the supports comprise upper portions, which are flat the lower portions, which are thin and are curved in cross-section to obtain strength combined with lightness.

I claim as my invention-` 1. The combination with a span-wire, of a plurality of conductor-supports loosely strung thereon to permit them to move longitudinally of the Wire when Stringing them, and permanent connections between said supports and independent of said span-wire and of the conductor to be supported for preserving the spacing of the supports after they have been strung upon the wire.

2. rlhe combination of the span-wire, of a plurality of conductor-supports each comprising a hook-shaped portion flat in cross-section and loosely fitting the span-Wire and a lower portion bent or curved in cross-section, and permanent connections between said supports and independent of said span-wire and of the conductor to be supported for preserving the spacing of the supports after they have been strung upon the wire.

3. The combination with a span-wire, of a plurality of cond uctor-supports loosely strung thereon to permit them to move longitudinally of the wire when sti-inging them, and permanent connections between said supports and independent of said span-wire for preserving the spacing of the supports after they have been strung upon the wire, each of said supports having a permanent opening to admit a conductor and having a hook-shaped upper portion which is Hat in cross-section to form an extended bearing on the span-wire and a lower portion for receiving a conductor, said lower portion being bent or curved in crosssection and having an opening to permit of the insertion of a conductor.

4. As an article of manufacture, a conductor-support formed of thin flat metal and comprising an upper or suspension portionflat in cross-section'and bent to fit the upper side of a span-wire and extend below the same and formed with holes at a distance below its upper bend to permit of the insertion of a fastening device in a plane below such span-wire, the lower conductor-supporting portion being' thin and curved in cross-section and formed with a permanent opening to permit of the lateral insertion of a conductor.

In testimony whereof I have signed my name to this specification, in the presence of two subscribingwitnesses, this 22d day of January, 1903.

FRED CHARLES LocKE.
